NOTE
If adjustments are made in (18) above, display readout will
indicate ADJ ' (step) 2, 200 Ps, 1 Ps. Repeat (14) through (19)
above until no adjustments are made in (18) above.
(20) If no adjustments were made in (18) above, display readout will indicate ADJ ',
(step) 4, 100 Ps, 1 Ps.
(21) Set oscilloscope calibrator for a CHAN 1, MARKER mode output of 5 s.
(22) Adjust ' control ccw until no further movement of B sweep display occurs. Note
position of first time marker of B sweep.
(23) Adjust ' control cw until 2d time marker of B sweep moves left and aligns with
position noted in (22) above.
NOTE
Movement of D REF OR DLY POS control at this point will
(24) Press and release upper TRIGGER COUPLING pushbutton. Display readout
will indicate Xl, Xl0, HRZ CTR, (step) 5, 10 Ps and two vertical cursors appear on the
display.
(25) Set oscilloscope calibrator for a CHAN 1, MARKER mode output of 10 s.
(26) If cursors are not aligned with 2d and 10th vertical graticule lines, adjust X1
GAIN (R860) (fig. 1), and HRZ CTR (R801) (fig. 1) to align the two cursors with 2d and 10th
vertical graticule line (R).
(27). If TI does not display 1 time marker per division l minor division, adjust Xl0
GAIN (R850) (fig. 1) for 1 marker per division (R).
(28) Press and release upper TRIGGER COUPLING pushbutton. Display readout
will indicate ADJ ', (step) 6, 10 ms, 100 Ps.
(29) Set oscilloscope calibrator for a CHAN 1, MARKER mode output of 10 ms and
adjust ' REF OR DLY POS control to intensify 2d time marker and ' control to intensify
10th time marker, and superimpose delayed sweep time markers within .2 division.
(30) Press and release upper TRIGGER COUPLING pushbutton and set
oscilloscope calibrator for a CHAN 1, MARKER mode output of 1 μs.
(31) For each step in table 23 do the following:
(a) Adjust ' REF OR DLY POS and ' controls as necessary, to intensify
indicated time markers on the A sweep and superimpose displayed B sweep time markers
within listed limits.
(b) Press and release upper TRIGGER COUPLING pushbutton.
